Comments
"Transport d'un convoi de Negres" (transportation of a convoy of Blacks) shows group of newly purchased, or about -to- be- purchased, slaves waiting to be taken into the interior. For an analysis of Rugendas' drawings, as these were informed by his anti-slavery views, see Robert W. Slenes, African Abrahams, Lucretias and Men of Sorrows: Allegory and Allusion in the Brazilian Anti-slavery Lithographs (1827-1835) of Johann Moritz Rugendas (Slavery & Abolition, vol. 23 [2002], pp. 147-168).
